PART 4: Memory and fractions
Part 4 covers memory and fractions. The calculator remembers numbers in 9 memories, keeps the last answer, and stores a function on each of the keys D1, D2 and D3. It then covers chain calculations and fractions.
Memory calculations
Example 14: memory calculations. The STORE key stores a number, the RECALL key recalls it, and ALPHA writes the letter of a memory in an expression.
Chain calculations
Example 15: chain calculations. The answer of one calculation can start the next one.
Fraction calculations
Example 16: fractions. The fraction key types a fraction. 2nd F with the same key types a mixed number. CHANGE turns the answer into a fraction or a decimal.
